running emacs 22... on ubuntu 9.04, fresh install.
When I copy a region of text via C-w (clipboard-kill-ring-save) then yank it back with C-y (clipboard-yank) it pastes random stuff, from some other buffer that isn't even open.
It was working fine earlier today and I haven't changed my emacs config.
Any ideas why this is suddenly happening/ how to fix it?
Thanks!
